No one can deny that the most important CS concept in this video is 101st computer science concept. You just simply cannot let grandma down
yes... and it is the hardest...
don't forgot about toster...
I mean, you are a computer scientist, so you should be able to fix every kind of electronic device of software.

F that. I had to work with MFPs in grad school teaching programming labs. Ye olde dot matrixe MFPs. I don’t know how much of the lab time was taken up by trying to get stuff to print for the students.
The only thing worse was the network delays which had a tendency to freeze students out for half the class.
I’m sure a number of times I wanted to say that I only work with software. You’re on your own for printer issues.
I had to fix the solar connection problem as well.
I saw your PFP and had to wonder what Karma Akabane would do if he knew CS and his grandma asked him for printer help.
As someone who just graduated with a CS degree, I can confidently say that you successfully condensed 4 years of my life into 13 minutes. Well done!
actaully just a gist not whole thing
not condensed but evoporate 🤣🤣
The lack of I type and J type instructions and the lack of MOVE.B type statements is something I observed..
Also the first fact already contains a mistake.
You did not learn any discrete math, stats, A.I., machine learning, Computer vision, computer security, etc? Because he only cover the surface.
I can imagine how overwhelming this video would've been for me if I watched it when I was a beginner, but this works very well for people who already have some experience in programming by summarizing and also including some concepts you may not have been aware of, but could understand easily if you spent some time learning about them.
@xFTOxGold It's alright, you'll get there, one step at a time. Don't try to skip over essentials that might make your life harder later on, and you'll be fine. A lot of self taught devs might brag about being able to land jobs after just 3 months but I'd argue it's probably a full year for the average person before they're job ready (that was the case for me too), and could take longer or shorter depending on the efficiency of your learning and since we're self taught, efficiency is a huge factor and could even be a matter of luck (nobody can truly measure their own learning efficiency as they're learning).
@xFTOxGold I started when I was 23 after wasting (arguably) 5 years in university, you're way ahead of me already. :) Good luck mate.
perfectly encapsulated
If someone is new to computer science should I maybe not send this to them? Idk if it will be helpful or scary.
As a beginner, some of this was genuinely helpful, but other things went over my head!! I am trying my best and definitely not giving up!
I could litterly see my 4 years computer science related subjects one by one, this is so amazing. Because even after knowing the subject or topic,it was very difficult for me to combine all of these and make some sense out of it. This connected dots so well for me,now I finally understood the digital,to computer organisation, data structures,class,algo, OS,Memory, Network subjects,that how all these get connected and work simultaneously. I wish I could have watched this earlier. This is by far the best video I have watched in my whole journey 🎉.
normally we are taught these things one by one and that too not in the correct order thats why we can't connect the dots simultaneously
we are taught these things in the order of their difficulty level
@@aniketsrivastava1870 I agree, I think every lecture/course should do this, the practical usage and how the subject is connected to it's large impact. Where exactly this is getting used, this is just a great story telling. This video for me was like watching an explanation video for a bad movie(my degree). I finally got the whole idea , but this should have happened while I was learning.
@@dhruvishah9077 wow looks like I found someone who literally hates there college education system just like me😄
This is like a great BBC series called CONNECTIONS that was hosted by James Burke and documented how one invention of the Industrial Revolution affected or led to another invention or even an entire industry. It threads the needle that weaves the fabric of our modern society.
I've been thinking on getting a degree in CS, Is it hard to find good jobs in that field?
It's fun how learning is more of a speedrun these days which acts as a very good starter, motivating us to learn the remaining stuff by ourselves and now we have something of a map which we can follow instead of blindly jumping into stuff.
That' a terrible way of learning
lol i had the same thought, i come from esports and getting my webdev cert feels like grinding rank in competitive 😅

Recursion too, a global variable for a recursive functions base case seems terrible.

Pretty nice video indeed, but it's kinda funny how the first fact already contains a mistake. "In theory, Turing machines can compute anything" was proven wrong by the same guy who came up with Turing machines.
There is an error at ~5:10. The Big and Little Endian examples are identical. EDIT: Also, at ~12:24, the IP address on the right is invalid. IPv4 addresses are limited to a maximum value of 255 (which is actually not available for unicast...).

You know, I'm currently doing my Master Degree in Computer Science and sometimes I think: I haven't learned anything during all that time.
Videos like that one show, how much stuff I see as self-evident in the meantime and furthermore how much besides of these basics I got to know during University.
If you're thinking about studing it, do it man! It's one of the coolest and mentally demanding things you can do and the best thing: I've heard and seen a lot of arrogant and overbearing people in other courses (especially in law and business administration) - in computer sciene it feels like most of the people are waaay more relaxed, really want to help you and it often feels more like a big family of nerds helping each other out (Stack Overflow - I love you) to fix problems without all of that pointless "I am better than you" - mindset.
Law schools have forced curves. You can't all get As, no matter how good you are.

4:40 it's actually called a float because the decimal point is 'floating' instead of 'fixed'. That is float gives you variable decimal precision instead of fixed point numbers that give you fixed decimal precision.

Yes. This video summed up what half of I've learned in the last 4 years in the Computer Science course at my University. I thought I would do more programming though, but they just explained the essentials, you will have to learn most of it on your own.

Thank you for always making such high quality, humor filled, and easy to understand videos on these topics.

Well, programming is such an unbelievably small part of computer science. What he lists here has almost nothing to do with it after turing machines and basic notions of numeric representations.
Truth be told, without a few years of dedicated study on things far more complicated than scripting, you almost have a right to be feeling like an imposter. Because you are, until you develop yourself.
It's cool you are working on this, but you have a long, long way to go before you can call yourself anything more than a hobbyist.
look into CS50, it is completely free and available online, taught by Harvard/Yale every year
it is their intro to computer science course, and will provide a very strong foundation. better than what you'd get in person at most highly ranked universities intro cs course actually
it is really good for people with zero programming experience, or someone who has had just maybe a AP computer science/intro to programming class
How does memory work, on the gates level?
Videos like this make learning a fun experience, great video!
I love how precise he explained design patterns as just "all kinds of other ideas"
5:09 I think there may be an error, the same image was used twice. I believe with little endian its actually 67, 45, 23, 01 from left to right (0x100 to 0x103)
ye little endian means the least significant bit/byte comes first, in memory/transfer order.
The image is indeed wrong.

Love the video, and it is crazy how much more detailed these topics really are. The amount of work that was put into developing all the technologies we have right now is crazy. For example, he talked about RAM and the CPU, but the computer architecture for how we access RAM ( l1 cache, l2 cache, page table etc) and the interaction with the CPU through different channels is such a mind boggling process.
My multi thousand dollar college journey in a 13 min video. 😭
Great video for topic reminders and to better inform me on other certain topics
Pretty much everything I have learned in computer science but in just 13 minutes and free of cost..
great content
There’s a slight mixup regarding static and dynamic languages: in a dynamic language you can actually change the type of a variable mid program.
This distinction is relevant for example in scala which is statically typed, but you don’t always have to declare types since it can infer the type from the provided value.
The video is correct. You can change data types in static typing via casting.
@@dawnfire82no you can't. Casting does not change the type of a _variable_ , it just allows you to put _value_ into variables of a different type. In statically typed languages, a variable (name of a memory addresses set) will have the same type during its lifetime. Most of the time you are even forbidden from creating aliases of different types to the same memory locations.
Wonderful, more please! As a cs major your language videos have been great for figuring out which languages I want to try in the future, and other videos have been great review material! Thanks Fireship!
Oh wow a year of computer science just in 13 minutes.
school is for dummies.
You summed me up my entire CS career. I brought me memories! Nowadays you used to forget most of thst stuff, it hapoens the more you keep working
I wish I watched this video yesterday when they asked me about algorithms and recursion in an interview. This is pure gold, you're the best!
3:34 I think the important part of dynamic typing is that types are determined at runtime, and not at compile time. What you described is type inference, and it is not tied to dynamic languages.
I came here to say the same thing. Haskell, for example, is statically typed and has type inference.
The important point is that you can change the type of a variable. This makes it impossible to infer the type statically in all cases. So dynamic languages have the overhead of having to track the type at run-time (and can't type-check or optimize statically).
It's pretty sad how popular JS & Python are while ML appeared 1973. Also crazy that TypeScript has static types and then we throw all information away and let the browser interpret JS...
@@RalfVogler This isn't entirely true either, since you can change the type of a variable in eg rust by redeclaring it.
@@Bwallker For the compiler it's a new variable that just uses the same name. I don't know Rust but I assume it's just shadowing the old binding or replacing it. That doesn't mean that you can change the type of a variable. In a dynamic language you could have a program point where you have a variable that has reaching definitions of different types (if random then x = 1 else x = "a") which can't happen in a static language.
@@RalfVogler *unless the language natively encompasses Union types, like Ceylon (though I think an associated definition is required or else inference fails, it's been a while since I've used Ceylon). Your point still stands though of course.
This video taught me more than my CS teacher in school ever could. Thanks for the amazing content man!
Thank you very much jeff, I have been a landscaper for the last ten years, for 6 months I watch at least one of your videos a day, thanks to you tomorrow I have my first interview as a software engineer

This is 1st sem of cs engineering syllabus crammed into a 15 mins video. Great job. Heard of the term Nibble after a long time!
Nice summary! I would just add one more concept about recursion and the call stack at 8:03 which is that some programming languages (mostly the functional ones) include something called tail recursion (or tail call optimization). Tail recursion doesn't keep pushing onto the call stack; instead it overwrites the last call on the stack with the recursive call, which can result in potentially infinite recursion with finite memory space.
If it overwrites the last call then how it returns from the call?
@@yousefali995 A stack frame consists of 1. The parameters to the function, 2. Memory allocated to hold all stack variables the function needs, and 3. The return address of the function that called it. In non-tail recursion, each recursive call allocates a new frame, with new parameters, new variable memory, and a new pointer that links back to the previous stack frame. But in tail recursion, the compiler optimizes it so each call just overwrites the previous parameters and variable allocations and reuses the return pointer, same as if you had just written a for-loop.
Great Video! It's really cool to see how different people have come with these ideas of structure that helped us create the internet. Knowing them is extremely important and It's great to have people like you sharing this content
I wish this video was existed when I was studying computer science. It is basically a visual dictionary of computer concepts. Brilliant!
it litteraly gone throught at least 85%cof my CS degree modules and it gave all the "why" which is the most important thing out there !
Thank you again for that awesome video !!!
Bro this chanel is soooooo good ❤ Didn't expect You to break it down to the real basics. liked & subbed
As someone with a Bachelors in Computer Science this video is pretty accurate and summarizes my college lessons pretty well in addition to giving me a confidence boost as I already learned 90%+ of these concepts. However, one area I definitely struggle in is printers as everyone expects me to be able to understand and fix their printers😂 Great video as always!
Reminds me of this - th-cam.com/video/N9wsjroVlu8/w-d-xo.html&ab_channel=RP
I knew most of it as a hobbyist without any CS degree, by just having a C64 (with a lot of computer basics in the manual already) since the 80s and later having picked up some C and web programming.
IT (Information Technology) is the study of how to fix broken computers. Computer Science is the study of how use a computer which is already in good working order. Comp Sci people are like race-car drivers and IT people are like car mechanics. If you learn both skills, then you can be a God among men.
This is like the first 6 months of University, but it was definitely very accurate lol
Missing some discrete math, no?
26 - “figures out the type automatically” can also refer to type inference, which is not the same as dynamic typing. Something along the lines of “figures out the type of a variable when it is used” would be more precise.
Strong/weak typing, dynamic/static typing and explicit/inferred typing have got to be THE most massively misunderstood concepts in the entirety of computer science. So much incorrect information that's confidently regurgitated around, even by popular trusted sources.
More precise? We have an average of 1 concept per 8 seconds over here. I don't believe that your wording would make any difference to the intended viewer.
This is EXACTLY what I needed. Precisely what I needed. Thanks!!!!
The way he went through all the concepts tells us how well he knows it all.
This is such an amazing summary of information. It really is incredible how succinctly you can explain these concepts.
A lot of information packed in only 13 minutes.Impressive man.
The way this flows together is honestly really impressive
Absolutely brilliant video. Helped me visualize all the concepts I've been learning and put them together
this video is so incredibly useful and informative, especially as a beginner software developer. thank you so much
I love the ending:
I've been developping for over 10 years now, and still there is 3 things I hate about computers
-> Printers (That stop to work for no reason)
-> Email setup (and all the additional shananigans that is added to "try" to prevent spam)
-> Routers (that you have to plug and unplug in a certain order otherwise they can't figure out by themself how to autoretry connection to the modem)
Printers in enterprise are a legit PITA. There's thermal receipt printers, they are their own special bit of fail, and we can go on forever about the different brands and interoperability with other brands and other OSes.
@@Sanchuniathon384 I remember the Linus tries Linux videos.... when Linus is surprised that his printer works out of the box on Linux!
I have been learning about programming and CS from 2020 on my own and it feels really good that I already knew almost all the concepts mentioned here, barring Little Endian and Big Endian.
ThankYou 101 🎉 special content from your channel , everything ❤
this is such a great video. Really well thought trough structure and sequence of topics. Also Everything concise and to the point. I love it!
(Kinda proud of myself for knowing each of the Concepts aswell^^)
You are incredible! I can’t imagine how difficult was putting all of this info together and make it flow into one another. This was both informative and a blast to watch 🔥
Amazing how well made your 101 videos are, great job.
thanks so so much! loved the video. made me, a begineer so much more oriented and confident :)
"It's called a shell because it wraps the kernal"
I know what a kernal and shell are, but surprisingly never realized that refrence.
I like to think of the shell as a plastic weapper around a piece of candy. 🍬
This was the whole 4 years of university explained in 13 minutes! This was fantastic!
Years of knowledge compressed into a few minutes. Great.
Explained concepts with well visualisation and connected
Wonderful content never I seen before like this great sir
Amazing video
Loved it
After a hectic day wasting all time in college and not learning anything, just to get a degree
This video was somewhat like, yeah atleast I did *something* productive
Maybe more videos like, you explaining solutions to some tricky questions, or explaining some data structure or algo in few minutes?
Great video! Always inspiring to see how you bring our world to a larger audience.
Unbelievable! This neat, simple and understandable. Thanks firehip 🔥🥳
Thank you! I've been searching for a channel like this for 4 months!
This is really great, perhaps consider other videos along this line for certain categories like machine learning or data science or game production or cyber security & cryptography.
Not even 30 seconds in and this is insanely accurate, I'm laughing, I'm crying, I'm learning. I'm experiencing an entire lifetime of emotions. Amazing videos man. lol keep up the great work. Thank you so much.

Wow! This is just an Awesome, Awesome video. Just flowed together starting with hardware. Bravo! 👏🏿👏🏿👏🏿
Damn a 13min video clarified the general definitions of 100 CS terms better than the 3 years in my CS degree program. Thank you.
I feel like I learned more about OS in this 13 minute video than I did an entire semester of Operating Systems...
Great video !
12:22 The server IP address, is not valid. An IP address (v4) is composed of 4 parts of 8 bits, so the biggest decimal number is 255.
Fairly sure he spammed a bunch of minor but obvious errors to get engagement. Calling TLS SSL is another. Difference between name and URL also got a bit confused. I attribute at least 50% of this as intentional engagement baiting rather than true mistakes :)
Going from OOP to Inheritance to the the gang of 4 book is another. Design patterns prefer composition over inheritance.
@@randomgeocacher To be fair SSL was more of an inacurracy than an error, since it was the protocol used before TLS and basically is the same thing. They just changed the name when the Internet Engineering Taskforce decided to improve the protocol. But technically speaking you are right.
also 12:12 domain name is a part of URL not alias to one
@@philippebaillargeon5204 People use SSL interchangeably with TLS. Or they say SSL/TLS.
wow. thank you!! i love videos like these so much.
Your videos are just awesome, short but too informative... Appreciate the work.
I did CS in college for a year as a sophomore. I ended up doing a medical drop due to my health and it has been about 4 years since. I had to get on disability because I couldn't work, so I eventually decided to try and do a bootcamp, to at least hopefully start a career remotely that I can do whether I am sick or not. All that to say I chose a part time 6 month Fullstack Academy web dev bootcamp and it has taught me so much in a very short amount of time. I learned far more in the 2+ months I've been in it than the full year of CS classes.
My CS classes used Java and they did not teach you how to use it at all. It had to be self taught and I did not expect that going into it. It was a huge challenge trying to keep up with learning the language while completing the required work. Most of the students had experience coding already which made their ability to absorb what was being taught way easier. After 4 years I had basically forgotten most of what I had learned syntax wise. So starting the bootcamp I was essentially a noob. But man not to advertise for them, but my instructors are awesome and like I said I have learned so much more than I ever could have alone. At least in a short amount of time like this. I'd say the course itself has taught 95% of these concepts. But I am only 2 months in out of 6 months. So here's hoping my coding career is fruitful and I can get my life back on track. Good luck to anyone else trying to get into this field!
Hey dude I hope things are going well.
been 4 months since you post this. hope u doing great!
Best of luck to you!
Hey i hope you're doing great, best of luck dude
This is a masterpiece of a video
Why did I not know about this channel? Love your work man, keep it going.
Wow, it was really good. Looking forward for more of these!
actually in 3:48 you should use double quotes for character array
This is the best video I've seen in the entire galaxy. The amount of information in such a small time is just amazing.
I would love to watch another video like this Jeff!!
Just like a fast train filled with all goods..exactly every scientist should know ..thanks alot for giving that link between each topics
The succinct style of this Computer Science summary is so refreshing compared to most of the fluff on TH-cam. Just awesome.
